| 摘 要： | 根据电缆隧道实际环境,建立电缆水平燃烧试验平台,研究不同火灾荷载和通风速度下,受防火涂料保护电缆延燃长度的变化规律。结果表明:一定风速条件下,电缆延燃长度随敷设宽度增加呈指数增长,可根据隧道内通风速度和电缆束宽度近似预测电缆延燃长度,从而为电缆隧道的防火设计提供依据。

| Abstract: | An experimental platform for horizontal combustion of cables was designed according to the tunnel environment,and the char length of cables covered with coating was investigated under different fire loads and ventilation conditions.The results showed that the char length grew exponentially with the cable laying width at a certain wind velocity and the length was predictable based on the ventilation and the width of bunched cables,thus it could provide the basis for the fire protection design of cable tunnel... |
